MRC Tech 7 780

DC “Power Packs” for model trains tend to be designed for HO scale trains, at least in North America. There are separate ones for G scale, and some multi-scale packs catering to both HO and larger scales. But those sold for N scale are typically just HO models, with the usual HO “16 volt” or higher output, usually called “Universal” power packs.

Anyone who’s been involved in model railroading for any length of time knows the Model Rectifier Corporation, more commonly just MRC. They’re probably the dominant supplier of DC power packs for HO and N-scale model railroading in North America, aside from those included in starter sets, although Kato’s Unitrack power pack likely gets a fair amount of N-scale market share. But I’ll admit I don’t have hard facts on market share for anyone.

My first power pack, after a cheap Tyco one that came in a starter set, was an MRC Throttlepack 501, circa 1972 (yeah, I’ve been doing this a while, although I took a long break after High School). That 501 still works today, although one of the switches has finally started having problems. But it survived 40 years of damp basements, being thrown in boxes for moves, and running a large variety of trains. That kind of quality leaves a lasting impression. I’d followed it with another MRC, a Control Master II, when I got back into model railroading and needed a second power pack (back around 1992). It too has served well, and still works. But both put out relatively high voltages (19V+), so I’d rather not use them with N-scale trains.

So when I started looking to see what was available in a modern design suited to N-scale, and discovered the MRC Tech 7 line had a model with a rated 14.5 V, 10VA output, it didn’t take me long to decide I wanted to give it a try. It’s a dual-cab power pack, with two independent throttles in one box. But I’m going to use it on a double-track line where I’m normally the only operator, so that’s fine.
